Radiesse uses calcium hydroxyapatite (CaHA) microspheres suspended in a gel carrier (sodium carboxymethylcellulose) which immediately gives volume when injected, and over time the CaHA stimulates the body’s own collagen production for longer-lasting structural support.
Because the microspheres form a scaffold under the skin, tissue builds up around them, which means Radiesse offers both an instant volumising effect and a collagen-stimulating, long-term rejuvenation effect.
No. Radiesse is composed of calcium hydroxyapatite (CaHA) microspheres in a gel carrier, not hyaluronic acid (HA).
In many patients, results last 12-18 months or more depending on treatment area, dose, metabolism and lifestyle.
Downtime is minimal. Some swelling, bruising or minimal discomfort may occur post-treatment, but most patients resume normal activities quickly.
Unlike many HA fillers which can be dissolved with hyaluronidase, CaHA fillers like Radiesse cannot be reversed in the same way. It is important to go to a qualified injector and have a clear treatment plan.
Radiesse is suitable for treating areas of volume loss (cheeks, temples, jawline), deeper wrinkles and folds (nasolabial, marionette), and in some practices, hand rejuvenation (back of hands) and structural support in the lower face.
Risks include the usual injection-related events (bruising, swelling, redness), and rare but more serious complications such as vascular occlusion if injected incorrectly. Because CaHA is non-HA, it has different handling and risk-profile compared to HA fillers. Good practice and injector experience are essential.
